The Dendera light is a motif in the Hathor temple at Dendera in Egypt. According to the hieroglyphic text surrounding the pieces, it depicts statues referencing part of the Egyptian creation myth . The temple, especially its crypts, contain several reliefs depicting statues of Harsomtus , sometimes syncretized with Ra , in the form of an ...
Light bending. Soldner is now mostly remembered for having concluded — based on Newton's corpuscular theory of light — that light would be diverted by heavenly bodies. In a paper written in 1801 and published in 1804, he calculated the amount of deflection of a light ray by a star and wrote: "If one substitute into tang ω the acceleration ...
Leitmotif associated with Siegfried's horn call in Richard Wagner's 1876 opera, Siegfried. A leitmotif or Leitmotiv [1] (/ ˌ l aɪ t m oʊ ˈ t iː f /) is a "short, recurring musical phrase" [2] associated with a particular person, place, or idea.
One of Eddington's photographs of the 1919 solar eclipse experiment, presented in his 1920 paper announcing its success. Henry Cavendish in 1784 (in an unpublished manuscript) and Johann Georg von Soldner in 1801 (published in 1804) had pointed out that Newtonian gravity predicts that starlight will bend around a massive object [15] as had already been supposed by Isaac Newton in 1704 in his ...
The precession of Mercury was already known; experiments showing light bending in accordance with the predictions of general relativity were performed in 1919, with increasingly precise measurements made in subsequent tests; and scientists claimed to have measured the gravitational redshift in 1925, although measurements sensitive enough to ...
Light bending may refer to: gravitational lensing, when light is "bent" around a massive object; refraction, a change in direction of a wave due to a change in its speed
Refraction and total internal reflection inside optical prisms can bend beams of light. This bending of the light allows it to be redistributed. Many small prisms may be joined at the edges into a sheet. A prism sheet is somewhat like a linear Fresnel lens, but each ridge may be identical. Unlike a Fresnel lens, the light is not intended to be ...
When a beam of white light passes from air into a material having an index of refraction that varies with frequency (and wavelength), a phenomenon known as dispersion occurs, in which different coloured components of the white light are refracted at different angles, i.e., they bend by different amounts at the interface, so that they become ...
